Chapter 3 Installing the IGX
Making Frame Relay Connections
Step 5 For optional Y-cable redundancy, configure the two cards by using the addyred command. For Y-cable
redundancy on a HSSI card, you must use port 1 of the cards for the primary and redundant ports. For
important information about Y-cable redundancy on a UFM-U, see the description in the UFM-U portion
of the Cisco IGX 8400 Series Provisioning Guide.
Step 6 Activate the ports using the upfrport command.
Step 7 Configure the port for DCE or DTE mode, speed, clocking, LMI type, and so on, by using the cnffrport
command. Alternatively, you can keep the default parameters. If you plan to bundle connections, use the
cnffrport command to set the Port ID to the DLCI planned for the near-end connections before you add
the bundled connections. The PortID is optional for nonbundled connections. Note that the cnfport
command functions the same for Frame Relay as the cnffrport command.
Step 8 Add connections by using the addcon command. Adding connections requires the slot number, logical
port number, and DLCI for each end of the connection. Frame Relay is a purchased option. If you attempt
to add connections but the system display states that Frame Relay is not available, see the “Obtaining
Technical Assistance” section on page xxiii.
If you do not know the Frame Relay class intended for entry with the addcon command, determine
which Frame Relay class number to use. Use the dspfrcls command to see the parameters that each class
specifies. To modify parameters in a class, use the cnffrcls command.
Step 9 Optionally—for an individual connection—you can configure bandwidth parameters or enable ForeSight
(if purchased) by using the cnffrcon command.
Optionally, you can set the channel priority by using the cnfchpri command. Normally, the
system-default priority is adequate.
Commands for T1/E1 Frame Relay
To specify logical ports on a T1 or E1 interface, use the addfrport command. The addfrport command
assigns a logical port number to a physical line and a range of 1 or more DS0s or time slots. Use the
logical port number to activate a port (using the upfrport command), add connections (using the
addcon command), or display statistics (using the dspportstats command). For example, after you add
logical port 14.60 2.1-24 with the addfrport command, you activate (up) this logical port by entering
the upfrport 14.60 command. The maximum number of logical port numbers on a UFM-C is 250. Use
the dspfrport command to display logical ports.
Deleting a Frame Relay Port
Delete a logical port by executing the delfrport command. Executing the delfrport command dissolves
any groups of DS0s or time slots and unassigns all DS0s or time slots on the logical port.
Note Before you delete a Frame Relay port, you must delete any connections on the port using the delcon
command.
After deleting a logical port with the delfrport command, you can deactivate the physical port with the
dnport command.
